The best prediction possible for the number of times you will roll a one number when a 6-sided die is rolled 12 times = (0.167)¹²

Events occur as the outcome of an experiment. But one cannot be satisfied with these events until a degree of measurement of the likeliness of its occurrence is not provided. Probability is a statistical tool used widely to obtain predictive value.

Here, 6-sided die rolled 12 times.

If a 6-sided die is rolled, possible outcomes are {1, 2, 3, 4, 5, 6}

So, total number of outcomes = 6

So, number of favorable outcomes = 1

Probability of getting 1 is 1/6 = 0.167

The quotient of the expression (5.04×10^12)÷(6.3×10^9) written in scientific notation is 8 × 10^2.

To divide two numbers written in scientific notation, we can divide their coefficients (the decimal parts) and subtract their exponents. So, we have:

(5.04 × 10^12) ÷ (6.3 × 10^9) = (5.04 ÷ 6.3) × 10^(12-9) = 0.8 × 10^3

Since 0.8 is less than 1, we can write this number in scientific notation by moving the decimal point one place to the right and subtracting 1 from the exponent:

0.8 × 10^3 = 8 × 10^2

Therefore, the quotient of the expression (5.04×10^12)÷(6.3×10^9) written in scientific notation is 8 × 10^2.

a) The price of the old model is P22,289.

b) The dimensions of the rectangle are 16 by 32.

a) Let x be the price of the old model. According to the problem, the price of the new 32'' LED television is P15,500 less than twice the price of the old model.

This can be expressed as 2x - P15,500 = P29,078. Solving for x, we can add P15,500 to both sides to get 2x = P44,578, and then divide both sides by 2 to get x = P22,289.

b) Let w be the width of the rectangle. According to the problem, the length of the rectangle is twice the width, so the length is 2w. The perimeter of a rectangle is the sum of the lengths of all four sides, which in this case is 2w + 2(2w) = 6w.

We are given that the perimeter is 96, so we can set up an equation: 6w = 96. Solving for w, we can divide both sides by 6 to get w = 16. Since the length is twice the width, the length is 2(16) = 32.

Answer: 26/100   OR     0.26  (I would put the answer as a fraction)

Step-by-step explanation:

We need both fractions to have the same denominator before we add them. The denominator of 6/100 is 100. The denominator of 2/10 is 10. We need to turn 10 into 100. To do that, we can do 10*10. This gives us 100. However what we do to the bottom must be done to the top therefore we have 20/100 + 6/100

Now the two fractions can be added together. 20/100 + 6/100 = 26/100.

Normally we would simplify this down to 13/50 but if you want it unsimplified 26/100 would be your answer.

a) The resulting true speed of the boat is approximately 5.39 m/s.

b) The compass direction of the boat is 21.8° south of east.

c) The distance downstream the boat will land on the shore if the river is 800 meters wide is 320 meters.

a) To find the true speed of the boat, we can use the Pythagorean theorem. Since the boat's speed is 5 m/s due east and the current's speed is 2 m/s due south, we can treat these as perpendicular vectors. The true speed can be found using the formula:

True Speed = √((5 m/s)² + (2 m/s)²) = √(25 + 4) = √29 ≈ 5.39 m/s

b) To find the compass direction of the boat, we can use the inverse tangent function. The angle θ can be calculated using:

θ = arctan(opposite/adjacent) = arctan(2 m/s / 5 m/s) ≈ 21.8°

Since the boat is headed east and the current is pushing it south, the true direction is 21.8° south of east.

c) To find the distance downstream where the boat will land, we first need to calculate the time it takes to cross the river. The boat's speed across the river (due east) is 5 m/s and the width of the river is 800 meters. The time taken to cross the river is:

Time = Distance / Speed = 800 m / 5 m/s = 160 seconds

Now, we can use the time to find the distance downstream by multiplying the current's speed (2 m/s) by the time:

Distance downstream = 2 m/s × 160 s = 320 meters

So, the boat will land 320 meters downstream from its starting point on the opposite shore.

The volume of the composite figure is 152 m³.

The volume of a rectangular prism can be found using the formula V = lwh, where l is the length, w is the width, and h is the height.

For the rectangular prism:

V_prism = lwh = 9m * 8m * 3m = 216 m³

For the cube:

V_cube = s^3 = 4m * 4m * 4m = 64 m³

Now, subtract the volume of the cube from the volume of the prism:

The value of the median is 18. The range of this plot is 6. The 25th percentile is 17 and the 75th percentile is 20. The interquartile range is 3.

We are given a box-and-whisker plot and we have to find the correct value of the median, range, 25th percentile, 75th percentile, and inter-quartile range with the help of this box-and-whisker plot.

We find the median with the help of the box. The line which splits the box into two halves is the median for the given data. Therefore, the median will be 18. To find the range, we subtract the minimum value from the maximum value. The minimum value is 15 and the maximum value is 21. Therefore, the range will be (21 - 15) = 6.

From the plot, we can see that the 25th percentile is 17, Q1, and the 75th percentile is 20, Q3. Now, we have to find the interquartile range. To find the interquartile range, we subtract Q1 from Q3. Therefore, our interquartile range will be (20 -17) = 3.

The maximum height of Anna's golf ball is approximately 7.81 units.

The equation y = [tex]x - 0.04x^2[/tex] represents the height of Anna's golf ball, where x is the horizontal distance the ball has traveled.

To find the maximum height of the ball, we need to determine the vertex of the parabolic equation. The x-coordinate of the vertex can be found using the formula x = -b/2a, where a = -0.04 and b = 1.

x = -b/2a = -1/(2(-0.04)) = 12.5

So, the maximum height of the ball occurs when it has traveled a horizontal distance of 12.5 units. To find the maximum height, we substitute x = 12.5 into the equation:

To find the parametric equations for a line in the direction of the vector 57 - 7 and through the point (0, 0, - 3), we can use the vector form of the equation of a line:

r = r0 + tv

where r is a point on the line, r0 is the given point (0, 0, -3), t is a parameter, and v is the direction vector (57, -7, 0).

Substituting the given values, we have:

r = (0, 0, -3) + t(57, -7, 0)

The perimeter of Koch's snowflake fractal will be infinite.

Koch's snowflake fractal is created by adding triangular bumps to the sides of an equilateral triangle at progressively smaller scales. At each stage, the number of sides of the resulting figure increases by a factor of 4, and the perimeter of the figure increases as well.

To see how the perimeter changes as bumps are added to all sides of the figure, we can use the fact that each bump adds a segment of length 1/3 to the original side. So if we start with a triangle of side length 1 and add a bump to each side, the new perimeter is:

P = 3(1 + 1/3) = 4

Now we have a figure with 12 sides. If we add a bump to each of these sides, the new perimeter is:

P = 12(1 + 1/3 + 1/9) = 16/3

In the next stage, we have 48 sides, and each side has a length of 1/3^2, so the new perimeter is:

P = 48(1 + 1/3 + 1/9 + 1/27) = 64/3

At each stage, we can see that the perimeter is multiplied by a factor of 4/3. So if we carry on this process forever, the perimeter of Koch's snowflake fractal will be infinite.

Using the formula V = k*T/P to get the volume, the required volume in the given situation is 1.77L.

The measurement of three-dimensional space is volume. It is frequently expressed quantitatively using SI-derived units, as well as several imperial or US-standard units.

Volume and the notion of length are connected.

The area that any three-dimensional solid occupies is known as its volume.

These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

So, the volume can be obtained using the equation:

V = k*T/P

The value of the constant k is:

K = PV/T = 16N/cm²*2.2L/340K = 0.104N*L*K⁻¹*cm⁻²

We can now determine the volume when:

T = 408 K

P = 24 N/cm²

V = k*T/P = 0.104N*L*K⁻¹*cm⁻²*408K/21Ncm = 1.77L
